If one angle is 67° and the other is 52°, the other two angles are equal and the angle has a value of 120°.
what is angle ?A place where two lines converge creates an angle. They are quantified in degrees and are denoted by the symbol °. Four essential types are reflex, acute, right, and obtuse angles. A circle has 360 degrees. One terminal exists when two rays (half-lines) are merged form an angle. The rays are referred to as the angle's sides, occasionally as its legs, and occasionally as its arms, while the latter is referred to as the angle's vertex. The place where all points of an angle converge is known as the vertex.

1. ¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) ∴ ¬(Q ∧ P) ∨ (T ∧ R)
2. [(T ∨ Q) → (T ∨ S)] ∨ [(T ∨ Q) → (T ∨ S)]
Given statement solution is :- Regardless of the values of T, Q, and S, the whole Valid Statements & Implications is always true.
Let's analyze the two given statements:
¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) ∴ ¬(Q ∧ P) ∨ (T ∧ R)
To prove this statement, we can use logical equivalences and deductions:
¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) (Given)
¬{[¬Q ∨ (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) (Implication equivalence)
¬{[(¬Q ∨ ¬S) ∧ (¬Q ∨ R)] ∨ ¬P} → (¬P ↔ P) (Implication equivalence)
¬{(¬Q ∨ ¬S ∨ ¬P) ∧ (¬Q ∨ R ∨ ¬P)} → (¬P ↔ P) (De Morgan's Law)
(Q ∧ S ∧ P) ∨ (¬Q ∧ P) → (¬P ↔ P) (De Morgan's Law)
At this point, the formula ¬P ↔ P is a contradiction. The left side (¬P) states that P is false, while the right side (P) states that P is true. Therefore, the whole statement is always true, regardless of the values of Q, S, and P.
Since the statement is always true, we can conclude ¬(Q ∧ P) ∨ (T ∧ R) is true as well, making the second part of the question valid.
[(T ∨ Q) → (T ∨ S)] ∨ [(T ∨ Q) → (T ∨ S)]
In this statement, we have two identical sub-statements connected by a logical OR operator.
If we assume that (T ∨ Q) → (T ∨ S) is true, then the whole statement is true, regardless of the values of T, Q, and S.
If we assume that (T ∨ Q) → (T ∨ S) is false, then we need to check the other part of the statement.
Assuming (T ∨ Q) → (T ∨ S) is false means that (T ∨ Q) is true, but (T ∨ S) is false. In this case, the second part of the statement [(T ∨ Q) → (T ∨ S)] is true.
Therefore, regardless of the values of T, Q, and S, the whole Valid Statements & Implications is always true.

A rectangle has 2 sides that are each 6 centimeters lo[ng. The perimeter is 22 centimeters. How long are the other sides?
Answer:
The other sides = 5 centimeters.
Step-by-step explanation:
Let's assume the length of the other two sides of the rectangle is "x" centimeters.
A rectangle has two pairs of equal sides. Therefore, we can set up the equation for the perimeter of the rectangle:
Perimeter = 2(length + width)
Given:
Length = 6 centimeters
Perimeter = 22 centimeters
Using the equation, we can substitute the given values:
22 = 2(6 + x)
Simplifying further:
22 = 12 + 2x
Subtracting 12 from both sides:
10 = 2x
Dividing both sides by 2:
5 = x
Therefore, the length of the other two sides of the rectangle is 5 centimeters.

a librarian has weekends off and has 10 paid vacation days per year, including holidays that fall on weekends. If his salary is 32,500 per year, what is his pay per workday?
his pay per workday will be $127.45.
How to calculate interest?Thus, the formula for calculating simple interest is J = C i t, where J is interest, C is principal, i is interest rate, and t is time. That is, J represents the amount added to the initial value, the capital is the calculation basis, the interest rate is the percentage applied on the capital and time is the capitalization period.
Knowing that:
10 paid vacation days per yearsalary is 32,500 per yearThe total weekends in a year:
52 * 2 = 104 weekend days.
Total paid vacation days, including holidays that fall on weekends:
10 - 4 = 6 paid vacation days.
Total non-working days:
104 + 6 = 110 non-working days.
Total working days in a year:
365 - 110 = 255 working days.
Pay per workday = Annual salary / Total working days
= $32,500 / 255= $127.45
Therefore, the librarian's pay per workday is approximately $127.45.

Line s has a negative slope.
Line s
is steeper than line r.
Line s is steeper than line
Line r

Answer: To determine which statement is true about lines r and s, we need to compare their slopes.
The slope of a line can be calculated using the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
For line r, using the points (-5, 2) and (-3, 8):
slope_r = (8 - 2) / (-3 - (-5))
= 6 / 2
= 3
For line s, using the points (-6, 4) and (2, 12):
slope_s = (12 - 4) / (2 - (-6))
= 8 / 8
= 1
Now, let's analyze the statements:
Line r is steeper than line s. (False)
Since the slope of line r (3) is greater than the slope of line s (1), this statement is true.
Line r is steeper than line (Incomplete statement)
This statement is incomplete.
Line s has a negative slope. (False)
The slope of line s (1) is positive, not negative. So, this statement is false.
Line s is steeper than line r. (False)
Since the slope of line s (1) is less than the slope of line r (3), this statement is false.
Line r has a negative slope. (False)
The slope of line r (3) is positive, not negative. So, this statement is false.
Based on the analysis, the true statement about lines r and s is:
Line r is steeper than line s.
Using the image below, answer the following question: you are asked to pick 2
marbles out of the bag, what is the probability of picking a blue marble and then a
green marble, without replacing the blue one?
Please
The probability of picking a blue marble and then a green marble without replacing the blue one is 2/15.

Find the sum of the finite series:

Answer: 59,048
Step-by-step explanation:
To find the sum of the given finite series:
Σ2· (3)n-1
n=1
where n ranges from 1 to 10, we can use the formula for the sum of a geometric series.
The formula for the sum of a geometric series is:
S = a * (r^n - 1) / (r - 1)
In this case, a = 2 (the first term of the series) and r = 3 (the common ratio).
Using the formula, we can calculate the sum:
S = 2 * (3^10 - 1) / (3 - 1)
= 2 * (59049 - 1) / 2
= (118098 - 2) / 2
= 118096 / 2
= 59048
Therefore, the sum of the given finite series is 59,048.
how many triangles?(urgent)
There are 75 triangles that can be formed using these 9 vertices.
Here we have,
We have 9 vertices arranged in a pattern where 5 vertices are above and 4 vertices are below in a parallel direction.
And we want to know how many triangles can be formed using these vertices.
In order to this,
Count the number of ways to choose 3 vertices from the 9 vertices.
This can be done using the combination formula, which is:
[tex]^{9}C_{3}[/tex] = 9! / (3! * (9-3)!)
= 84.
Since,
A degenerate triangle is one where all three vertices lie on the same line. To count the number of degenerate triangles,
We need to count how many ways we can choose 3 vertices that lie on the same line.
There are 5 lines with 3 points each (the 5 lines with the upper vertices). So the number of degenerate triangles is:
5 [tex]^{3}C_{3}[/tex] + 4 [tex]^{3}C_{3}[/tex] = 9.
Subtract the number of degenerate triangles from the total number of triangles to get the number of non-degenerate triangles.
Therefore, the number of non-degenerate triangles is:
84 - 9 = 75.

Question Find the distance between the two points. (12, 5), (−12, −2)
Answer:
Distance between points is 25 Units.
Step-by-step explanation:
To find the distance between two points, we can use the distance formula. The formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Given the two points: (12, 5) and (-12, -2), we can assign the values as follows:
(x1, y1) = (12, 5)
(x2, y2) = (-12, -2)
Plugging the values into the distance formula, we get:
d = sqrt((-12 - 12)^2 + (-2 - 5)^2)
= sqrt((-24)^2 + (-7)^2)
= sqrt(576 + 49)
= sqrt(625)
= 25
Therefore, the distance between the points (12, 5) and (-12, -2) is 25 units.

how do you find out the area of a tent, floor included
To find the area of a tent, including the floor, we need to measure or determine the dimensions of both the tent's floor and any additional areas such as vestibules or extensions.
Floor Area: Measure the length and width of the tent's floor in the same unit of measurement (e.g., feet or meters). Multiply the length by the width to calculate the floor area. For example, if the length is 8 feet and the width is 6 feet, the floor area would be 8 feet * 6 feet = 48 square feet.Additional Areas: If the tent has vestibules, extensions, or any other separate areas, measure each area's dimensions and calculate their individual areas separately.Total Area: Once you have calculated the individual areas of the floor and any additional areas, simply add them together to find the total area of the tent, including the floor. For example, if the floor area is 48 square feet and there is an additional vestibule area of 10 square feet, the total area would be 48 square feet + 10 square feet = 58 square feet.Learn more about the area of the tent here:

The probability of the digestive tract disease, given a positive test result, is 45%.
A. Two-Way Frequency Table:
Let's create a two-way frequency table to represent the situation:
Test Positive Test Negative Total
Disease Present A B 5,000
Disease Not Present C D 95,000
Total 5,000 95,000 100,000
In this table:
A represents the number of sheep that have the disease and test positive.B represents the number of sheep that have the disease but test negative.C represents the number of sheep that do not have the disease but test positive.D represents the number of sheep that do not have the disease and test negative.B. Probability of Disease Given Positive Test Result:
P(Disease | Positive)
= (P(Positive | Disease) x P(Disease)) / P(Positive)
= 0.94 x 0.05 / P(Positive)
To calculate P(Positive), we can use the law of total probability:
P(Positive) = P(Positive | Disease) x P(Disease) + P(Positive | No Disease) x P(No Disease)
So, P(Positive | No Disease) = 1 - P(Test Negative | No Disease)
= 1 - 0.94 = 0.06
P(No Disease) = 1 - P(Disease) = 1 - 0.05 = 0.95
Now, P(Positive) = (0.94 x 0.05) + (0.06 x 0.95)
= 0.047 + 0.057
= 0.104
Finally, we can calculate P(Disease | Positive):
P(Disease | Positive) = (0.94 x 0.05) / 0.104
= 0.047 / 0.104
≈ 0.452

What is the difference in height of Mount St. Helens?Height refers to vertical distance from the top to the object's base. Occasionally, it is also labeled as an altitude which measures from down to top of a surface.
To get difference in height, we will subtract the height after the eruption from the height before the eruption:
Given:
Height before eruption = 2.95 kilometers
Height after eruption = 2.55 kilometers
Difference in height = Height before eruption - Height after eruption
Difference in height = 2.95 km - 2.55 km
Difference in height = 0.4 kilometers
0.4 kilometers to metres will be:
= 0.4 * 1000 metres
= 400 metres.

What are the side lengths of triangle Graph shows a triangle plotted on a coordinate plane. The triangle is at A(minus 7, 3), B(minus 3, 6), and C(5, 0). Type the correct answer in each box. If necessary, round any decimal to the nearest tenth. units units units
With the coordinate provided, the lengths of the triangle are Side AB = 5 units, Side BC = 10 units and Side CA = 12.4 units.
How do we find the sides of triangles using coordinates?To find the side lengths of the triangle using the coordinates provided, we use the distance formul.
The distance between two points (x1, y1) and (x2, y2) is given by √((x2-x1)² + (y2-y1)²).
Side AB: Distance between A(-7, 3) and B(-3, 6)
= √((-3 - -7)² + (6 - 3)²)
= √((4)² + (3)²)
= √(16 + 9)
= √25
= 5 units
Side BC: Distance between B(-3, 6) and C(5, 0)
= √((5 - -3)² + (0 - 6)²)
= √((8)² + (-6)²)
= √(64 + 36)
= √100
= 10 units
Side CA: Distance between C(5, 0) and A(-7, 3)
= √((-7 - 5)² + (3 - 0)²)
= √((-12)² + 3²)
= √(144 + 9)
= √153
= 12.4 units

Given f(x)=4x^2 - 1 and g (x) = 2x- 1 , find each function
1. ( f+g )( x )
2. ( fg ) ( x )
3. ( f^n ) ( x )
The values of the composite functions are
(1) (f + g)(x) = 4x² + 2x - 2
(2) (fg)(x) = 8x³ - 4x² - 2x + 1
(3) (fⁿ)(x) = (4x² - 1)ⁿ
How to evaluate the composite functionsFrom the question, we have the following functions that can be used in our computation:
f(x) = 4x² - 1
g(x) = 2x - 1
Using the above as a guide, we have the following:
(f + g)(x) = f(x) + g(x)
(f + g)(x) = 4x² - 1 + 2x - 1
Evaluate the like terms
(f + g)(x) = 4x² + 2x - 2
(fg)(x) = f(x) * g(x)
(fg)(x) = (4x² - 1) * (2x - 1)
Evaluate the products
(fg)(x) = 8x³ - 4x² - 2x + 1
(fⁿ)(x) = (f(x))ⁿ
So, we have
(fⁿ)(x) = (4x² - 1)ⁿ
